Classification of voice modes using neck-surface accelerometer data

Michal Borsky, Marion Cocude, Daryush D. Mehta, Matías Zanartu, Jón Guðnason

ICASSP 2017accepted

This study analyzes signals recorded using a neck-surface accelerometer from subjects producing speech with different voice modes. The purpose is to explore if the recorded waveforms can capture the glottal vibratory patterns which can be related to the movement of the vocal folds and thus voice qua…

Evaluation of speech inverse filtering techniques using a physiologically based synthesizer

Jón Guðnason, Daryush D. Mehta, Thomas F. Quatieri

ICASSP 2015accepted

Glottal inverse filtering methods are designed to derive a glottal flow waveform from a speech signal. In this paper, we evaluate and compare such methods using a speech synthesizer that simulates voice production in a physiologically-based manner that includes complexities such as nonlinear source-…
